Документ Morphometric characteristics of the rat small bronchi in consumption of the complex of food additives(Полтавський державний медичний університет, 2022) Eroshenko, G. A.; Donets, I. M.; Shevchenko, K. V.; Lysachenko, O. D.; Solod, A. V.; Vatsenko, A. V.; Ulanovska-Tsyba, N. A.; Єрошенко, Галина Анатоліївна; Донець, Ілона Миколаївна; Шевченко, Костянтин Васильович; Лисаченко, Ольга Дмитрівна; Солод, Анатолій Вікторович; Ваценко, Анжела Володимирівна; Улановська-Циба, Наталія АркадіївнаThe paper presents the data of the morphometric study of the small bronchi of the lungs of rats under the complex effect of food additives. It has been established that consumption of the complex of food additives leads to a change in the morphometric parameters of the structural components of the small bronchi of the rat lungs, which at the early stages is manifested by a significant decrease in the morphometric parameters of the outer diameter and lumen with a significant increase in the height of the epitheliocytes in the small bronchi of all orders due to the primary endogenous impact of the components of the food additive complex, which is associated with spasm of the exchange blood vessels and the progressive phenomena of hypoxia. Subsequently, the impact of the alterative factor, which prevails over the protective mechanisms of the body, is manifested by the development of bronchospasm in the small bronchi of the 3rd order, the appearance of inflammatory infiltration in the bronchial walls and the formation of bronchial hyperreactivity, which is characteristic of the development of diseases of the respiratory system, including asthma.Документ The role of sulfide anion in the developmen of oxidatives stress in the liver under conditions of chronic alcoholic hepatitis(Полтавський державний медичний університет, 2022) Mykytenko, A. O.; Akimov, O. E.; Eroshenko, G. A.; Neporada, K. S.; Микитенко, Андрій Олегович; Акімов, Олег Євгенович; Єрошенко, Галина Анатоліївна; Непорада, Каріне СтепанівнаThe pathogenesis of alcoholic hepatitis is multifactorial and is the final result of a complex interaction of ethanol metabolism, inflammation and immunological reactions. The molecular mechanisms of H2S action in alcoholic hepatitis have not been sufficiently studied, and its protective role has not been proven. The experiments were carried out on 30 white, sexually mature outbred male rats, weighing 180–220 g. The animals were divided into 2 groups: І – control (n=6); ІІ group – animals on which we simulated alcoholic hepatitis. In the homogenate of the liver of rats, the activity of superoxide dismutase and catalase, the concentration of malondialdehyde and oxidatively modified proteins, sulfide anion concentration and the production of superoxide anion were determined. A decrease in the concentration of sulfide anion against the background of an increase in the activity of superoxide dismutase and the presence of an inversely proportional strong correlation between them indicates the effect of alcohol on the thioredoxin system, namely, on the increase of expression of a protein that interacts with thioredoxin, stimulating the reaction of the latter with reactive oxygen species. Chronic alcohol intoxication leads to the development of oxidative stress in the liver of rats due to an increase in the production of reactive oxygen species. The decrease in the concentration of sulfide anion on the 28th day of the experiment is connected with its usage as an antioxidant.
